- 1 0 all whom it may concern;

Be it known that I, CHARLES A. PAUL, a citizen of the United States, and resident of Portland, county of Multnomah, State --of Oregon, have invented a certain new and useful Improvement in Stove Attachments for Automobiles, of which the following is a specification.

The object of my invention is to provide a stove which may be carried about as an attachment for an automobile, for example being fastened on the rui'iningboard of the latter, which will beheated by the exhaust gases of the motor of the automobile.

A further object is to sojconstruct this stove that it maybe used as an open plate to broil or fry, and also that it may be used as an oven. 7 v V A still further object of my invention is to provide a stove which may be readlly attached to the exhaust pipe of an automobile and injcombination therewith to pro vide means by which the flow of the exhaust gases'through'theexhaust pipe may be controlled, so that the same may be deflected in whole or in part into the stove.

A still further object ofmy invention is to construct the stove so that the exhaust gases will be retained therein for as long a period as possible without unduly retarding their rate' of flow therethrough, and'to provide means for this purpose which at the same time will adapt the stove to serve as a muffler and in this way eliminate any increase in back pressure to the exhaust of the motor relatively to the back pressure of 'an ordinary m-ufl'ler, as used at the present time. I

Astill further object of my invention is to provide a stove which is inexpensive to manufacture and easy to assemble being made with a demountableibody section which when removed provides a -flatlheat ing plate which is suitable for fryingand broili'ng, and when the demountable body section is placed onflthe heating plate it constitutesf therewith an oven which inc identally p'rovidesan, enclosure for the 'food protecting the same from the windandtdust while it is being :cooked' and also serves, when disconnected from the BXlIQlIStlDlPG, V asa storingplace foi food' while on a journev.

prising a hollow base adaptedto be supported on the automobile running board having an inlet at one end and connected with the exhaust pipe of the automobile and provided with an outlet at the opposite, end. I provide a flexible conduit which connects the exhaust pipe with said inlet and a valve which controls theflow of the exhaust gases through said exhaust pipe and which is adjustable to deflect thes'alne in whole or in part into said hollow base. The base is provided with transverse baflles spaced alternately from the opposite sides of the base which form a circuitous pas sageway of substantially uniform cross sec- .tion from said inlet tosaid outlet, and 1 also provide an open top body section-demountable on the base and provide a cover which sea-ts onthis body which has spring controlled locking means for fastening the cover and therewith the body, to said base.

I I illustratethe construction and operation of my device in the accompanying drawings, in'which: y

My improved automobile stove is adaptedfor'use'on any standard automobile as a, and ispreferably carried on the foreward part of" the running board 5. The stove placed in, this position will permitthe full opening otthe'front door 0 and also My stove is made up with an integral casting e which forms the upper portion of the base and which is provided with an inlet duct f and an outlet duct 9. Theinlet duct is connected with theexhaust pipe 72 of the short section of pipe 9 which leads the gases away from the stove andpreferably downwardly, so that it will not affect the mechanism of the automobile.

I provide a lower base 2' on which the casting 6 seats which has achannel portion or peripheral groove 2" around its edge which is substantially the same width as the thickness of the walls of the casting e. The walls of the casting 6 thus can seat inside of this channel and form a tight seal for the stove. Screws j fasten the casting e to the lower base, i and hold the side walls in the channel. Thecasting e is provided with a number of baflies 7a which are spaced from the side walls at alt-ernate ends. These baffles are substantially parallel and "thus the gases in passingthe ends of the baffles must travel along a circuitous path.

The spacing between the battle plates and the ends of the battles and the side walls is substantially equal, and thus the passageway: for'the gases is substantially uniform in cross section throughout its entire length.

:The pulsating effect of the separate explosions of the exhaust, -therefore, will be expanded gradually and thus the sound of the explosion is materially decreased. The stove heat given off to the stove of course, is;

utilized in cooking food. The upper surface of the lower base i fits tightly against the transverse baffle 72 so that the stoveis cn closed on both sides of the baffles and thus til - .all of the gas is caused to pass along the circuitous path, in the manner previously described.

. I preferably place a sheet of asbestos Z or other similar heat insulating material on the under surface of the based, so that the heat iven off from the stove willnot radiate c ow-nwardly and thus injure the running board or other portionof the car to which thestove is faste ned. The asbestos or other .heat' insu latingmaterial is preferably held i-i-r-pla'ee'by a section Oflllttil sheeting whieh is l fast ened to thebase 2' by studs-m".

*The base is provided-With legsn which space. the same from the running board and t .e legs are provided wrt'hholes a -t'hro-ugh into the flexible section of tube 7t. has a pivoted gate w inside, which controls which bolts or screws may be placed so as to hold the stove firmly in position. The upper surface of the main casting e is substantially flatand has a continuous upstanding flange oaround-its edge so that the surface of the stove is substantially a basin like surface, which-will thus hold the food, and will prevent it from falling off the stove in case the automobile, and therefore the stove, is standing at a slight angle.

I provide a substantially dust proof covering bod 1 p which [its on top of the-casting e and which seats on theoutside of the casting 6 as shown in Fig. 4 and rests upon the ledge g. The body '7) is provided with removable cover 1" which has a handle r :for readily removing the same. 'I also provide locking rods 8 which "are held in operative position. between the bifurcated lugs g on the main casting e and the similar registering lugs t on the cover 37. The lockingrods 8 are provided with springs a which bear against the slidable nut 2/ on. one-end and the flange 10 on the other which is apart of the rod u. placed in the bifurcated lug t it is necessary to compress the spring a so that the lower end of the rod can be caught under the concave bifurcated lug g" on the base 6. Theslidable nut a", the upper face of which is convex, is then caught under the lug and the handle 8 of the locking rod 8 is caught over the lug t onthe cover and thus holds the cover tightly in position I I provide a valve o -in the exhaust pipe h which has a side opening 4) which opens This the passage of the gases through-thee haustpipe and to the stove. In one posi tion, as shown inFig. "i, this gate w seats against the end of one section of the exhaust plpe h, as at w, and in its other position, as

shown in dotted line, it seats against the end of the pipe h as at 2 This gate is controlled by a handle'e, so that it may cause all of the gas to pass through the stove or it may prevent any of the gas from passing "through, or it may be at any point in between the complete the pipe.

This gatethus serves as a means for reg=uclosure or opening of latingthe heat of the stove because it regulates the amount of gases which arepermitted to pass through the stove. If only a small portion of the'gases a-re permitted to pass-through the stove-the heat" content not be very great, and therefore; the

stove will not be heated to'avery high degree. If all of the gases,' however, areperinittedto pass through the stove "the resultant" heat will be increasedproportionately.

I claim: 7 1. stove-to be heated by theexh-aust gases :of aaeng-ine,camp-rising" an; integral casting including a top plate having a depending edge Wall, and baffles extending from the top plate for the full height of the edge Wall and alternately projecting from and terminating short of opposing portions of such edge Wall, a bottom plate having an edge channel to snugly receive the edge wall of the top plate, and means to secure the bottom plate to said'edge wall, said bottom plate when in place directly contacting with the lower edges of the baffies to thereby define atortuous passage in the space between the top and bottom plates, said passage having an inlet and outlet at the respective ends thereof.

2. A stove to be heated by the exhaust gases of an engine, comprising an integral casting including an imperforate top plate having a depending edge wall and an upstanding edge flange to form a basin-like surface with the top plate, baiiies depending from the top plate and extending from the edge wall, and a bottom plate removably secured in sealing relation with the free edge of the depending edge wall of the top plate to form with the baffles a tortuous exhaust gas passage within said edge wall and between the top and bottom plates, the edge wall being formed with openings at the re:

spective ends of such passage to provide for the inlet and outlet of the exhaust gases.

3. A stove to be heated by the exhaust gases of an engine, comprising an integral casting including an imperforate top plate having a depending edge wall, and an upstanding flange at the edge of the top plate, with the inner surface of the flange merging into the surface of the top plate, said top plate being formed with a ledge immediately beyond said upstanding flange, baffles secured to the top plate and to the edge wall, a removable bottom plate secured to the edge Wall to define with the battles a tortuous exhaust gas passage Within the edgewall and between the top and bottom plates, and a cover removably seated on said ledge and bearing against the outer surface of the upstanding flange of the top plate.
